The aim of this research is to provide a principled account of the generation of embedded constructions (called parentheticals) and to implement the results in a natural language generation system. Parenthetical constructions are frequently used in texts written in a good writing style and have an important role in text understanding. We propose a framework to model the rhetorical properties of parentheticals based on a corpus study and develop a unified natural language generation architecture which integrates syntax, semantics, rhetorical and document structure into a complex representation, which can be easily extended to handle parentheticals. . | An Integrated Architecture for Generating Parenthetical Constructions Eva Banik Department of Computing The Open University Walton Hall Milton Keynes Abstract The aim of this research is to provide a principled account of the generation of embedded constructions called parentheticals and to implement the results in a natural language generation system.

They are not part of the main predicate-argument structure of the sentence and are marked by special punctuation . parentheses dashes commas in written texts or by special intonation in speech. Syntactically parentheticals can be realized by many different constructions . appositive relative clauses 1a non-restrictive relative clauses 1b participial clauses 1c or subordinate clauses 1d . 1 a The new goal of the Voting Rights Act more minorities in political office - is laudable. wsj1137 b GE which vehemently denies the government s allegations denounced Mr. Greenfield s suit. wsj0617 c But most businesses in the Bay area including Silicon Valley weren t greatly affected. wsj1930 d So far instead of teaming up GE Capital staffers and Kidder investment bankers have bickered. wsj0604 A common characteristics of parentheticals is that they express information that is not central to the meaning of the overall message conveyed by a text or spoken utterance and since they are specifically marked by punctuation or intonation they allow the reader to
